Desperate to make some more headway on this project bike. 😅

I figure you folks might want a visual of where this thing is at. I wish I had more photos of it the day I brought it home to compare, but I got right to wrenching on it at the time. Teardown is nearly complete, paint to follow. I got a front end + rear wheel from a 1979 CB750F Super Sport and...

I've checked and haven't been able to find complete sets or even lone calipers beyond a couple of listings for trashed, incomplete parts. Trying not to pay for master cylinders I won't use or lines that need replacement anyway, if possible.

I have a 1979 CB750F front end going on my project bike. It did not include any of the brake hardware at all, and I'm having trouble locating part numbers or replacement options. Anyone know where I can source some calipers, mounts, etc?

That's no problem, the original was already completely ruined so I'll look out for a larger replacement if I pick this front end up. From my research on it so far it seems like the 1979 900's forks are 35mm, same as the '78 750s.

I'm looking at this front end that looks like a 79 CB900F (EDIT: it's a 1979 CB750F, got a better pic of the VIN plate) setup with the dual disk brakes on reverse comstars and black sliders, it's got the ducktail fender. Because of the condition of the comstars on my '78 Hondamatic project I'd...

Got it, thanks for clarifying!

The petcock is ruined so it's of no concern to save; I'll be sure to plug the vent lines up so they don't get covered. Are there any products that would help remove old sealing? Acetone maybe?

Hi folks, long time with no post. My last thread about this bike is here; I first picked it up in January '23. I put this project to the side for a long time and finally have a moment with enough time/money/motivation to make some more progress and wanted to follow up with you fine folks in case...

Let's see if I'm lucky. I could certainly use the help getting my '78 roadworthy! Sorry, computer had a hiccup!

Alright, so I got spark the other day. Cleaning and reseating connections and rechecking the gaps, and she got something. It's not consistent though, so I'm probably going to end up doing a lot of rewiring. Great. I got her fired up on starter fluid a few times. Revved high immediately every...

In the latest news, the starter is fixed and the electric start button works. I also fixed the killswitch, it was turned the wrong way and the bearing wasn't seated in the grooves so it just slid around rather than "clicking" between off/run/off. Cleaned up the contacts of course, so that should...

Quick update: I confirmed the starter is bad. It's completely seized up so I opted for a replacement rather than rebuild because I found a used/working OEM unit cheaper than a rebuild kit. I already have the new starter and will be installing it tomorrow. My setback was the points cover. It...

I cleaned up a lot of the grounds, not only for starter/ignition parts but across the board, and tested continuity where I could, everything (so far) has turned out alright with just a little cleaning but I'll have to check in on this when I have more time to go over it.

I did check the wire before anything and didn't notice any looseness, breaks, or anything. Meant to check continuity but didn't have my meter sitting there to remind me. Tapped the starter with a mallot several times before/during retesting and never got a sign of life. I've ordered a...

Tensioner isn't off yet since I have to worry about getting the points cover off first; will do that though. I made sure to be in neutral and gauge light works to confirm. Here's hoping the torque converter is good since everything else seems to be bad. Jumping the starter straight to battery...

I got some more parts off today. The current goal is to confirm engine will run before stripping down entirely, but I figured I would go ahead and start pulling things off while waiting on replacement parts. I confirmed that the starter is bad, and similarly expensive to attempt a rebuild...

Hey everyone, I'm brand new to the CB scene and grabbed this CB750A for a low price in untested, unknown condition, just under 5K miles. I got to take a look before buying and aside from a lot of surface rust and aging parts I think it will run again soon. Full disclosure, I have worked on cars...
